I tried them one by one, and will note my observations. XaaNoScreenToScreenCopy: Shifting windows seems a bit better, but not much. Still some artifacts. Fonts still not good. Moving windows slow. XaaNoScanlineCPUToScreenColorExpandFill: Fonts OK now. Moving windows still artifacts. XaaNoPixmapCache: No positive effects XaaNoOffscreenPixmaps: No positive effects XaaNoMono8x8PatternFillRect: No positive effects. XaaNoSolidFillRect: No positive effects. As none of these alone cures all problems, I repeated the test with all options enabled, then remove one by one until problems re-appear. All options enabled: same result as the combined results of XaaNoScreenToScreenCopy and XaaNoScanlineCPUToScreenColorExpandFill: XTerm fonts OK, shifting windows better, but not perfect, and slow. Didn't trust my memory, so tried again with only option NoAccel. All problems gone, and shifting windows seems faster than with Option XaaNoScreenToScreenCopy. > BTW, what architecture is this? Intel Celeron 466, XFree 4.2.0, i810 chipset, Gentoo Linux. ATI Technologies Inc 3D Rage IIC 215IIC [Mach64 GT IIC] (rev 58). If it helps, I can do another compile and see what options were set, because Gentoo is a 'compile-it-yourself' distribution where options are tailored to the system you run it on.

Yes, replace that Option "NoAccel" with one or more of the following (starting with the most likely culprit(s)) Option "XaaNoScreenToScreenCopy" Option "XaaNoScanlineCPUToScreenColorExpandFill" Option "XaaNoPixmapCache" Option "XaaNoOffscreenPixmaps" Option "XaaNoMono8x8PatternFillRect" Option "XaaNoSolidFillRect" Let me know which mininal set of the above cure all artifacts.

I did not see any follow-up on these posts, and I'm having the same problems. To me, it seems that it is caused when screen content is blitted from display memory to display memory. It appears most pronouncedly when I'm moving a window horizontally. Also, in a Konsole, I notice that pixels of characters are randomly absent. I think that part of video memory is used as a font cache, so this could be indicative of hardware blitting problems also. I tried the Option "NoAccel", and problems disappeared. This also seems to point in the direction of hardware blitting trouble. Any more tests I can do? Henk. ___ Xpert mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/xpert
